Hardware considerations

GitHub Enterprise requires a persistent data disk separate from the root disk. For more information, see "System overview."

For your storage device, we recommend a high-performance SSD, either directly attached or from a storage area network (SAN).

Based on your seat count, we recommend this hardware configuration:

Seats

vCPUs

Memory

Attached Storage

Root Storage

10-500

2

16 GB

100 GB

200 GB

500-3000

4

32 GB

250 GB

200 GB

3000-5000

8

64 GB

500 GB

200 GB

5000-8000

12

72 GB

750 GB

200 GB

8000-10000+

16

128 GB

1000 GB

200 GB

These are minimum recommendations. More resources may be required depending on your usage, such as user activity and selected integrations.

Note: The root disk can be resized by building a new appliance or using an existing appliance. For more information, see "Increasing storage capacity."

Warning: We recommend you use webhooks to fetch repository changes for continuous integration (CI) or similar systems. Regular automatic checks, or polling, will significantly reduce the scalability of your instance. For more information, see "About webhooks"

Creating the GitHub Enterprise instance

To create the instance, you'll need to import the GitHub Enterprise image to your virtual machine and attach an additional storage volume for your instance data. For more information, see "Hardware considerations."

In XenCenter, import the GitHub Enterprise image you downloaded. For instructions, see the XenCenter guide "Import Disk Images."

For the "Enable Operating System Fixup" step, select Don't use Operating System Fixup.

Leave the VM powered off when you're finished.

Create a new virtual disk to use as an attached storage volume for your instance data, and configure the size based on your seat count.
For instructions, see the XenCenter guide "Add Virtual Disks."

Configuring the GitHub Enterprise instance

Copy the VM's public DNS name, and paste it into a web browser.

At the prompt, upload your license file and set a management console password. For more information, see "License files."
